Nige's Diet & Nutrition Blog: How eating sugar & starch can lower your insulin needs.

This is a bookmarking post. Jason Sandeman is a chef who has a couple of web-sites at Well Done Chef! and Jason Sandeman — Real Food For Your Life. He has Latent Autoimmune Diabetes of Adulthood (LADA), which has resulted in a total loss of his pancreatic beta cells which means that he has to take insulin.

Now, it's generally believed in low-carb circles (and by myself) that people with Type 1 Diabetes Mellitus (T1DM) should minimise their intake of sugary & starchy carbohydrates as these promote wild fluctuations in blood glucose. See The problem with Diabetes.

Jason wrote the following comment on Richard Nikoley's blog. The relevant part is as follows:-
"Even more weird – now that I have introduced the starches into the diet – I have actually got better control now. I thought my insulin needs would go up – but they haven’t. They’ve gone down."

To which I replied:-
"How about this for an explanation? You now have a well-controlled glucose input to your circulation via diet, which has suppressed the poorly-controlled glucose input to your circulation via hepatic glucose production."

Hepatic glucose production (HGP) is increased by Glucagon, Cortisol & Adrenaline/Epinephrine. These are secreted as blood glucose level falls below certain values in order to keep our brains alive. See
Blood Glucose, Insulin & Diabetes.

As keeping our brains alive is rather important (!), the mechanism is fairly crude in operation and blood glucose can overshoot in a positive direction, as a bit of glycation is less harmful than brain death. See
"Funny turns": What they aren't and what they might be. Hyperglycaemia requires insulin to lower blood glucose back to the normal range.

Therefore, eating some (but not too much) sugar & starch can result in lower blood glucose level and lower insulin secretion. Eating fibre/fiber (a carbohydrate) is also good for keeping blood glucose low, as only just mentioned in
Fiber and Insulin Sensitivity. Ain't the human body weird?
